Organic compounds are commonly used to the material in the modern industry, is an important part in industrial production, the chromium oxide is a kind of compound, it is a light green to dark green small six square crystal. When it's hot, it turns brown. Crystal extrahard. Very stable, even in the heat of the hydrogen flow under no change. Potassium bromate solution in heating, slightly soluble in acid and alkali, almost insoluble in water, ethanol and acetone. And irritation.
Chromium, chemical symbol Cr, elemental metal for the steel gray. Element's name comes from the Greek, meaning "color", because chromium compounds have colors. In 1797 the French chemist walker orchid (L.N.V auquelin) in the Siberian red lead chromium (lead) find a new mineral, the next year with carbon reduction. Chromium content in the earth's crust is 0.01%, the highest in 17th.
Silicon is one of the half metal, old name "si". Melting point is 1420 ℃, the density of 2.34 grams per cubic centimeter. Qualitative hard and brittle. At room temperature does not dissolve in acid, soluble in alkali. The nature of the metal silicon and germanium, lead, tin, is in the nature of semiconductor. Silicon in the earth's crust is of rich resources, second only to oxygen, accounting for more than a quarter of the total weight of the earth's crust, in the form of silica or silicate.
Strontium titanate is a kind of inorganic compounds, molecular formula for SrTiO3, strontium titanate can be used as electronic ceramic materials and artificial stones.
Strontium titanate (SrTiO3) as the typical perovskite structure, and is toxic chemicals, is a function of a wide range of electronic ceramic material, with high dielectric constant, low dielectric loss, the advantages of good thermal stability , and is widely used in electronics, mechanical and ceramic industry.
Silver-grey aluminum metal, the relative quality of 26.98 points, relative density 2.55, 99.5% purity aluminium melting point is 685 degrees, the boiling point of 2065 degrees, melting endothermic 323 kj/g, aluminum reducibility, extremely easy oxidation, heat emission in the process of oxidation. Oxidation sharply when heat release 15.5 kj/g per gram, aluminium is ductile metals, easy processing. Metal aluminum oxide film on the surface of the transparent membrane, and has good chemical stability.
Crystallization cinereous powder, cobalt powder with irregular shape. Cobalt powder according to their chemical composition and physical properties are divided into, FCo - 2, FCo FCo - 1-3 three grades, the FCo - 1 for high performance of ultrafine cobalt powder, FCo to 2 for ultrafine cobalt powder.
Molybdenum powder is a kind of important inorganic minerals. From the Angle of geology, molybdenum powder is natural mineral of the earth's crust. Molybdenum powder ore deposit has three types: limestone, chalk and marble.
What is the ytterbium oxide? For this many people may not know, ytterbium oxide is a kind of coating material, here is introduced:
Ytterbium oxide, namely the Ytterbium trioxide (Ytterbium oxide) formula: Yb2O3; Molecular weight: 394.08;
Properties: white with pale green powder, density: 9.17 g/cm3, melting point: 2372 ℃, boiling point: 4070 ℃.
Properties: insoluble in cold water and acid, soluble in dilute acid.
Silica, chemical terms, the pure silica colorless, normal temperature is solid, chemical formula for the SiO ₂, insoluble in water. Does not dissolve in acid, but soluble in hydrofluoric acid and thermal phosphoric acid concentration, the can and molten alkali class work. Exists in the nature, which has two kinds of crystalline silica and amorphous silica.
